    	Neptune is the eighth planet from the Sun which is approximately 4.5 billion km. To bring Neptun's size into perspective if the Sun was a door, earth would be the size of a nickel and Uranus would be the size of a baseball. One day on Neptune lasts 16 hours earth time. A complete orbit around the Sun for Neptune takes about 165 Earth years.  Neptune was the first planet located through mathematical predictions rather than through regular observations of the sky. Urbain Joseph Le Verrier was the first to notice the mass that caused the change in Uranus's Orbit. He was ignored by French astronomers so he sent his data and findings to Johann Gottfried Galle. The first night out in the Berlin Observatory Galle found Uranus using Verrier's data. Seventeen days later he also found Neptune's largest moon Titan. Neptune was almost named Le Verrier in honor of the astronomer's data that was used to find the planet. The international astronomical community denied the name and chose Neptune instead after the Roman god of the sea. Another interesting fact about Neptune is that Pluto's orbit goes inside Neptune's orbit for about 20 years, but they will never collide because of the immense distance between the two.

    	Neptune's main axis is tipped over by about 47 degrees compared with the planet's rotation axis. This tilted axis creates some interesting changes to the atmosphere of Neptune. The Bright blue color of the planet comes from the mixture of methane in the atmosphere. Neptune's winds can be three times more powerful than those found on Jupiter.  Neptune also has a storm that is visible as a large oval spot on the plant. This stormy spot is named the Great Dark Spot and it is large enough to contain the whole earth.

    	Neptune has a six known rings that are not uniform in shape and are thought to be young additions to the planet. Neptune also has 13 moons in total, six of them were discovered when Voyager 2 reached Neptune. This year there was a discovery of a new moon. Triton is Neptune's largest moon. This icy moon orbits in the opposite direction from the rest of the moons, this fact can mean that this moon was collected in Neptune's distant past, potentially making it Neptune's oldest moon.

            <p> It makes sense that Neptune was the first planet discovered using mathematical predictions, it is invisible to the naked eye, because it is so far from the Sun and Earth. This is also the reason why Voyager 2 was the first and only spacecraft to visit Neptune in 1989.
